SWITCH-STAN D.

SPECIFICATION forming part of Letters Patent No. 351,235, dated Qctcber 19, 1886.

Application filed June 1886. Serial No. 206,215. (No model.)

To (LZZ whom it may concern.-

Be it known that I, FREDRIO O. WEIR, a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Switch- Stands, of which the following is a specification.

My invention relates to aswitch-stand to be used in throwing rails for switching trains on railroadtracks.

The object of my invention is, first, to pro vide a parallel-moving switch-stand, wit-h a switclrbar having a direct connection to the sWitclrr-ails,withlever-connection,constructed so that a strong direct leverage may be obtained to move the rails.

Another object ofmy invention is to cheapen the construction and to thoroughly protect the parts from the weather.

Another object of my invention is to operate a switclrtarget simultaneously with the moving of the rails to show safety or danger, as the case may be.

Other objects of my invention will be set forth in the description of the accompanying drawings, making a part of this specification, in which Figure 1 is a perspective view of my invention; Fig. 2, a top plan view with the top of the case broken off; Fig. 3, a detail view of the moving cylinder.

A represents a casing made in two sections provided with flanges 1 2, through which bolts 3 are passed to fasten the sections together.

4 represents a horizontal wing or flange projecting horizontally from the casing A. It is provided with holes 5 for spiking the same to sleepers or ties on which they rest.

6 represents a shaft journaled in bearings 7 8,forined in the casing to receive said shaft. 9 represents a drum rigidly connected to said shaft 6. 10 represents a worm-slot pierced in said drum 9. 11 represents a lever attached to the square end of said shaft 6 for rotating said shaft and drum.

12 represents the switch-bar moving longitudinally in ways or openings pierced through the ends of housing 13, formed on the casing A. 11 represents a lug rigidly attached to said switch-bar 12, and projecting inwardly and resting within the spiral groove 10 of drum 9. As lever 11 is turned .l'orward or backward the lug 1 1 is moved forward or backward by the spiral groove 10,reciprocnting the switchbar 12 in its bearings.

16 represents a bevel-gear mounted upon shaft 6 at the end of drum 9, meshing with a beveled quadrant, 17, which is keyed upon the target-shaft 18. This shaft journals in hub 19 at the top of housing 20, in which the bevel-segment 17 is inelosed or covered'to protect it from the weather.

The casing A is cutaway between the housing 20 and the bevel-gear 16. This housing 20 is practically an extension of the casing A.

21 represents a target attached to shaft 18.

The bevel-gears 16 17 are constructed so as to turn the target 21 one-fourth of a revolution at each throw of the lever, so that the target may indicate danger or safety to the respective tracks,according to the position of the switch, which is operated by lever 11.

22 represents the switch-rails, 24 25 the stationary rails of the tracks to be cut in and out by the movement of the switch-lever.

This form of construction of switch is very cheap and durable.

It is obvious that great power may be ob tained in the direct thrust, capable'of switching the movable switchrails against the large amount of strain or resistance.

The casing A perfectly houses or protects all the working parts of the switch.

Having described my invention,what I claim 1. A switchstand composed ofa casing, A, having a housing, 13, at oneside and a housing, 20, at one end, a bar, 12, provided with lug 14., said bar being passed through the side housing, 13, and connected at one end to the switch-rail, a spirally-grooved drum, 9, journaled in the casing and engaged with the lug 14 of bar 12, the lever 11 and bevel-gear 1.6 on the shaft of said drum, and the target-shaft 18, having a quadrant-gear, 17, located in the end housing, 20, and meshing with the gear on the d'runrshaft, substantially as described.

2. A switch-stand composed of a casing, A, formed of two sections bolted together, one section having the recess 13 for the bar 12,and the separate compartment 20 for the signal, substantially as described.

In testimony whereof I have hereunto set my hand.
